| titleOfInvention | Synthesis method of 4, 4-aminodiphenyl ether |
| abstract | The invention discloses a synthetic method for aqueous phase synthesis of 4, 4-aminodiphenyl ether, belonging to the field of organic synthesis: adding 4-nitrochlorobenzene into water, adding potassium hydroxide and tetrabutylammonium bromide, and heating to react to obtain 4, 4-nitrodiphenyl ether. Adding 4, 4-nitrodiphenyl ether into water, adding hydrochloric acid and palladium carbon, introducing hydrogen, and heating to react to obtain 4, 4-aminodiphenyl ether. The method has the advantages of simple and convenient operation, no introduction of organic solvent in production, environmental protection, higher yield of the obtained product and suitability for large-scale production. |
